One conversation with your kids about not smoking isn't enough. Introduce the subject when a child is still very young, in simple language and with clear rules. As your child grows, repeat the message in terms he can relate to. Here are some suggestions to help you decide what to say, when to say it, and how.
Even if smoking is a hot-button issue for you, it's important that you remain calm and relaxed when raising the subject with your child. Keep it light. Nothing turns off teens and preteens more than a lecture. Don't do all the talking. Ask questions and truly listen to your child's answers, without judging.
In the activity "Find a Good Time to Talk", you'll find ideas on how you can initiate a conversation about not smoking, but at other times your child may open the door for a frank discussion. Be alert for these opportunities. If your daughter asks for permission to go to a party on Friday night, talk about the situations she might encounter there and how she can deal with them. If your teenage son is talking about the rules his high school coach has set down for the team, discuss some of the health reasons for those rules.
You know your child better than anyone, so you're in a great position to know which messages about not smoking may make the biggest impression. Here are some reminders of points you may want to make about smoking. Of course, you'll want to talk about these subjects in your own words, geared to your child's level of understanding.

If you think (or know) that your teen or preteen is smoking, you still need to talk about your values, and all the reasons not to smoke. The hardest part can be managing your own feelings of anger, disappointment or guilt. Resist the urge to punish or shame him, and don’t launch into a lecture; your child is likely to shut down and tune you out, just when you really need to have a conversation.
Instead, talk about things you’ve noticed (friends who smoke, clothes smelling like smoke). “I’m concerned that you might be thinking about smoking, or already using cigarettes.” Without accusing, talk about situations, people or feelings that might be encouraging him to smoke. Describe your concerns: “You know how I feel about smoking, and it’s very easy to get addicted to cigarettes.” Ask about some of the symptoms of cigarette addiction:33. Wellman, R.J. et al (2004). Short term patterns of early smoking acquisition. Tobacco Control, 13, 251-257.
And remember, smoking is not just a discipline issue, but a medical problem. Encourage your child to talk to her doctor and look for local resources that can help her quit. Ask her if she’s already considered quitting, and what her concerns are.
If she answers “no” to those four questions, or doesn’t want to talk, remind her how important this is to her future life and health, and that you plan to keep talking about it.
